1. How to choose the appropriate rectifier diode?
When making a choice, the following factors need to be considered:
Current capacity: Determine the maximum current that the diode needs to handle.
Reverse voltage: Ensure that the reverse voltage of the diode can withstand the highest voltage in the circuit.
Forward voltage drop: A lower forward voltage drop can improve circuit efficiency.
Recovery time: For high-frequency applications, choose fast recovery or Schottky diodes. -
2. What is the maximum reverse voltage (PIV) of a rectifier diode?
The Peak Inverse Voltage (PIV) is the maximum reverse voltage that a diode can withstand. When selecting a diode, the PIV must be higher than the maximum reverse voltage in the circuit, usually twice or more the input voltage.

3. What is the difference between a single rectifier diode and a bridge rectifier?
A single rectifier diode can only rectify the positive half wave of AC power (half wave rectification), while a bridge rectifier composed of four diodes can rectify the positive and negative half waves of AC power (full wave rectification), with higher efficiency and smoother output.

4. How to identify the polarity of a single rectifier diode?
Rectifying diodes usually have polarity markings, with the positive (anode) of the diode being "+" and the negative (cathode) being "-". On the packaging of diodes, there is usually a circular mark on the cathode side indicating the direction of the diode.
